One reason for the emergence of firms such as Aptera is that designing a new vehicle has become as much an exercise in software simulation as in metal (or even carbon-fibre) bashing.

之所以Aptera这样的公司出现，就是因为新车型的设计已经很大程度上变成了计算机仿真技术的运用，而不只是依赖于金属(或者是碳纤维)。

In fact, virtual reality is exploiting software and hardware of the computer to generate a simulation of an environment, such as an easeful classroom, a breathtaking action and so on.

实际上，虚拟现实就是利用计算机的软件和硬件去产生一种境界的仿真，如仿真一个学习场所，一次惊险的行为等等。
